SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 506,246, dated October 10, 1893.

Application filed October Z6, 1892. Serial No. 450,011. (No model.)

To all whom it may concern.-

.l 3e it known that I, GEORGE E. MILLER, a citlzenof the United States, residing at St. Louis, 1n the county of Gratiot and State of Mlohigan, have invented a new and useful Spring-Bed, of which the following is a specification. j

My invention relates to improvements in spring-beds; the objects in view being to pro- Vlde a spring-bed that may be conveniently handled, and which shall possess durability as well as simplicity1 and cheapness, and will be so constructed as to give perfect ease and comfort to the occupant.

With these general objects in view the inventlon consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings--Figure 1 is a planview of a spring-bed embodying my inventlon. Fig. 2 is a longitudinal sectional view through one of the bed-sections. Fig. 3 is a side elevation. Fig. 4 is a transverse section. Fig. 5 is a detail view of the U-shaped ba1l and the transverse wire.

Like numerals indicate like parts in all the figures of the drawings.

In practicing my invention, I prefer to form the bed-bottom in two sections, which if deslred, may be hinged together and adapted to fold one upon the other, though they may be independent if preferred. Each section consists of a pair of opposite longitudinal side bars 1,, which are connected adjacent to their ends by transverse foot and head bars 2, whose ends are let into the side-bars, thus forming two rigid oblong frames.v To each of the transverse bars near the ends thereof there is secured a pair of eye-bolts 3, that may be adjustable, and each pair of eye-bolts 1s loosely connected to a pair of coiled springs 4. These pairs of springs have their inner ends connected to perforations formed in the ends of longitudinally-disposed spring strips 5, preferably formed of metal, but which may be formed of wood if desired. These strips extend parallel to each other and in a longitudinal direction. They are surmounted at intervals by intermediate transverse-bars 6, o whose ends project beyond the strips but doA said pair of convolute springs.

not quite contact with the inner surface of the side-bars 1. Surmounting these bars 6 is a series of convoluted springs 7, and each of these springs is connected at its upper end to the adjacent springs by means of short coils of wire 8.

At the foot and head of the bed are located U-shaped wire bails 9, and the same have their opposite terminals inwardly bent to form transversely-disposed bearing portions 10, that are journaled in eyes l1 located upon each of the side-bars 1. Beyond these eyes the terminals extend into the frame and downwardly and nally rest under the ends 0f those bars 6 that are at the ends of the series, whereby the U-shaped frames are stened. A transverse wire l2 connects the terminals of each of the bails, and the ends of the wire, after being coiled about said terminals depend from the frames, as shown at 13, pass through guide-eyes 14, and have their lower ends bent to form stops 15. As the frames rise and fall with the weight thereon, these depending portions serve as guide-rods and reciprocate throughv the eyes, their upward movement being limited by the lower ends of the rods contacting with the eyes.

Ooiled wire springs 16 connect the convolute springs 7 that are on the end bars 6 with the transverse wire of the frames, and said transverse wire is in turn by links connected with the transverse portions of said frames.

A pair of convolute springs 17 surmount the head cross-bar, and short sections of coiled wire 18 are connected to the links and to the The foot section, however, in lieu of the convolute springs, preferably employ rings 19, which are connected by means of the short spring-wire sections to the links. Pairs of wire-strands 2O are connected to the rings, diverge, and pass round the upper coils, the convolutes of the first convoluted springs cross each other, engage With the second pair, recross and re-engage, and so on throughout the series, and finally connect with those convoluted springs that support the head portion of the bed. Short limiting chains 22 are at intervals connected with the side bars of the bed-frame, and have their upper ends connected to a convenient portion of the convolute springs, thus limiting the upward movement of the latter.

This completes the construction of the bedbottom, and it will be seen that by reason of the fact that it is formed in two sections, the same may be readilyhandled, that is removed and replaced upon the bedstead, is readily accessible for any purpose whatever, such as cleaning or repairing, yet in any position constitutes but a single bed. It will further be apparent that the foot and head portions are preserved against sinking or sagging, as are also the sides and other portions of the bottom, the Whole being braced in all directions and combining to lend ease and comfort to the occupant.

Having described my invention, what I claim is 1. In a bed bottom, the combination with the rigid frame, of the opposite U-shaped wire frames at the head and foot of the frame, the intermediate convolute springs, the spring suspended frame within the rigid frame and on which the convolute springs are mounted, the transverse Wires l2 extending across the ends of the bed bottom, connecting the U- shaped frames and depending below the same in the form of guide wires 13 and formed with stops at their lower ends, said guide wires passing through guide eyes on the frame, the coiled wire springs 16 connecting the end convolute springs with the wires 12, a pair of springs 17 arranged at the head of the bed bottom, the rings 19 and coiled springs 16 at the foot of the bed bottom, and the pairs of wire strands connected to the rings, diverging and passing around the upper coils of the first pair of convolute springs, then crossing each other and engaging with the second pair, and so on throughout the length of the bed, the other ends of the Wire strands being connected with the springs 17 at the head of the bed, all substantially as described.

2. In a bed bottom, the combination with the rigid frame, of the opposite U-shaped wire frames at the head and foot of the Stute, the intermediate convolute springs, the

spring suspended frame within the rigid frame and on which the convolute springs are mounted, coiled springs at each end of the bed connected to the U-shaped wire frames, and wire strands to connect the coiled springs with the convolute springs, said strands passing around the upper portions of the lirst pair of convolute springs, then crossing each other and engaging with the second pair of convolute springs, and so ou throughout the length of the bed, all substantially as described.

3. In a bed-bottom, the combination with the oblong frame, the `eye-bolts adjustably mounted in the ends of the frame, springcoils connected to the eye-bolts, resilient strips connecting the inner ends of the coils, bars supported on the strips, the convolutedsprings mounted on the bars, and short coils of wires connecting each convolute with its neighbor, of opposite U-shaped wire-frames at the head and foot ot' the bed-bottom, the terminals of said wire-frames having intermediate bends or bearing-portions, eyes connecting the same loosely with the bed-bottom frame, said terminals beyond the eyes ex..

tending below the frame and engaging with the transverse convoluted spring-supporting bars and spring connections between the U- shaped frames and those convoluted springs at the foot and head of the bed, substantially as specified.

4:. In a bed-bottom, the combination with the oblong bed-frame, transverse bars, and convolute springs arranged thereon, of opposite U-shaped frames pivoted to the sides of the bed-frame, and at their lower ends engaging under the transverse bars, and springconnections between the convolute springs and said U-shaped frames, substantially as specied.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

GEORGE E. MILLER.
